They are Generation C-connected, communicating, content-centric, computerized, community-oriented, always clicking. As a rule, they were born after 1990 and lived their adolescent years after 2000. In the developed world, Generation C encompasses everyone in this age group; in the BRIC countries, they are primarily urban and suburban. By 2020, they will make up 40 percent of the population in the U.S., Europe, and the BRIC countries, and 10 percent in the rest of the world-and by then, they will constitute the largest group of consumers worldwide.

Unit of Work. What factors influence human population growth trends most strongly, and how does population growth or decline impact the environment? Does urbanization threaten our quality of life or offer a pathway to better living conditions? What are the social implications of an aging world population? Discover how demographers approach these questions through the study of human population dynamics.

But securing the future will require fixing a system that has become a joke.

By Rachael Brown Chart: "The Happiness Index" Times were tough in 2009. But according to a cool Facebook app, people were happier. By Justin Miller On August 25, 2008, two little boys walked into public elementary schools in Southeast Washington, D.C. Both boys were African American fifth-graders. The previous spring, both had tested below grade level in math. One walked into Kimball Elementary School and climbed the stairs to Mr. William Taylor's math classroom, a tidy, powder-blue space in which neither the clocks nor most of the electrical outlets worked. The other walked into a very similar classroom a mile away at Plummer Elementary School. In both schools, more than 80 percent of the children received free or reduced-price lunches. At night, all the children went home to the same urban ecosystem, a zip code in which almost a quarter of the families lived below the poverty line and a police district in which somebody was murdered every week or so.

After a year in Mr. Taylo

"The animals found in the south eastern Australian State of Victoria are unique and diverse. Detailed descriptions of animals, maps of distribution, and endangered species status combine with stunning imagery and sounds to provide a valuable reference that can be used in urban, bush and coastal environments. The content has been developed by scientists at Museum Victoria, Australia's largest public museum organisation. The app holds descriptions of over 700 species encompassing birds, fishes, frogs, lizards, snakes, mammals, freshwater, terrestrial and marine invertebrates, spiders, and insects including butterflies. From animals found in rockpools, minibeasts in your garden, to wildlife you might see in the bush. We've put in a lot of species, but it's still a fraction of the complete fauna of Victoria. Our scientists will continue to add additional species and refine descriptions over time."

teachers are being deskilled, unceremoniously removed from the process of school governance, largely reduced to technicians or subordinated to the authority of security guards. Underlying these transformations are a number of forces eager to privatize schools, substitute vocational training for education and reduce teaching and learning to reductive modes of testing and evaluation.

Three legends can be seen as variations on one central theme, namely, that it is the learner who knows best and that she or he should be the controlling force in her or his learning. Digital natives, learning styles and learners as self-educators are all discussed.
